ELISA is the most commonly used quantitative detection technique in biological experiments and clinical testing. The accuracy and reproducibility of experimental results highly depend on standardized sample addition procedures and controlled incubation conditions. Most issues in ELISA experiments, such as false positives, false negatives, numerical deviations, and large inter-well differences, are not due to reagent quality but result from improper control of three core details: temperature, time, and light protection.

Western Blot (WB), also known as protein immunoblotting, is used to separate and identify specific proteins from complex mixtures and is a widely used basic protein analysis method.

This study adopted a progressive research framework: “mIF spatial panoramic screening + deep‑learning‑based quantitative modeling + single‑cell mechanistic validation”. Multiplex immunofluorescence was the core platform for data acquisition and signature mining. Specimens were enrolled from 553 surgically treated NSCLC patients at stage IA‑IIIB with strict inclusion and exclusion criteria. Post‑operative disease‑free survival (DFS) was selected as the primary clinical endpoint.

Unlike traditional immunohistochemistry, which is limited to detecting a single protein marker, multiplex fluorescent immunohistochemistry can simultaneously label multiple biomarkers on a single tissue section, fully preserving the native tissue structure, cell locations, and intercellular interactions, providing critical technical support for tumor microenvironment analysis, new therapeutic target discovery, and immunotherapy regimen optimization.

ELISA blocking is a crucial step in the enzyme-linked immunosorbent assay, and the effectiveness of blocking directly determines the experimental background, signal-to-noise ratio, and the reliability of the final data. In practical experiments, many people encounter various issues in selecting the blocking solution, setting incubation conditions, and troubleshooting abnormal results.

Pluripotency is the ability of a cell to differentiate into cell types of the three germ layers, the endoderm, ectoderm and mesoderm. It is a property shared by embryonic stem cells, embryonic carcinoma, and induced pluripotent cells.

ELISA is a fundamental immunoassay technique widely used in biological experiments, scientific research testing and clinical laboratory diagnosis. Beginners often get confused about its principles, workflows, classifications, detection range and other basic concepts. This article organizes core ELISA knowledge in a FAQ format to cover common blind spots and help novice researchers quickly master key points of ELISA.

This study reconstructs the application logic of the technology, focusing on in-depth discussions around its detection results, data characteristics, subtype analysis, and mechanistic conclusions, clarifying its core value and application advantages in the study of RIF immune mechanisms.

Induced pluripotent stem (iPS) cells, are a type of pluripotent stem cell derived from adult somatic cells that have been genetically reprogrammed to an embryonic stem (ES) cell‑like state through the forced expression of genes and factors important for maintaining the defining properties of ES cells.
